When cutting fabric how do you line up your fabric edge with the lines??? Do you do it the same with every cut, like inside the line, outside the line or middle of the line??? I took a class on precision piecing and she said to always put the edge of the fabric right in the middle of the line... On the Omnigrid ruler there is a tiny space between the lines and she said to have the fabric edge just showing in that space... I have been doing this and it seems to be making my piecing much more accurate...
